Named after Dr. Ignatio Mobius, the research station is a large installation rising high above the Tiberium glaciers. Inside, life support units create a safe, breathable atmosphere - no hazmat equipment is necessary to survive within (unless you're at Level 5, where autonomous life support is necessary).
Michael McNeil is stationed at the facility and is present during a time of increased activity from the Threshold. This prompts GDI to dispatch a Commando, Ricardo Vega to examine the alien device. He is assisted in his operation by a Nod Priestess, Maja, a secret informant within the Brotherhood of Nod. The examination of the Threshold Tower leads to the discovery that it is being activated by the Scrin who dispatch invasion forces against Earth through the newly opened portal. The Mobius Research Station is shortly after attacked by Scrin walkers and destroyed.
